Batman is a very old comic book character invented by Bob Kane for DC Comics in 1939.
But since then he has been re-invented, portrayed as good and bad and played by many different actors. Each of these actors had different suits and style. Each also played Bruce Wayne in a different way, giving their personality to the character.
So Ive started a poll at the bottom of this post to find out which is the favourite Batman. Below is a brief look at the different actors who played Batman over the years.
